3600 Serial Interface Puzzler

2001-03-27 Thread Gareth Hinton

Further to my post regarding 2600's a few days ago.
I received an e-mail from Rick Thompson (Thanks) as below:

I have run across the same thing with the 3600
routers.  It counts the first serial card as 0, no
matter if it is in slot 0 or 1.

Rick Thompson

so I decided to drag a 3600 out and try a few things.

Working with an NM1E2W:

Inserted a WIC1T into slot w1 - This becomes S2/0 (Strange but agreeing with
previous findings).
Configured S2/0 with IP address and WR MEM.
Powered down and inserted another WIC1T into slot w0.
The new WIC1T now becomes S2/0.
With both interfaces configured I powered down and removed w0. The card in
w1 becomes S2/0 again.

Is this a standard fact for all modular routers that the first card inserted
will become 0, no matter which slot it's in, or is this platform/IOS
specific?

Cheers,

Gareth

I believe the interfaces on the 2600/3600 series are numbered from right to
left but only slots with modules in them are counted.  So, if you have a WIC
in the rightmost slot, it is--in your example--S2/0.  If you then add the
other WIC, that one is S2/1.

If you leave the rightmost slot empty and put a WIC in the left slot, that
is S2/0.  

They are numbered from right to left, and bottom to top, if applicable.
